Abstract

The invention discloses an activated dye ink suitable for ultra-high-speed digital printing and a preparation method thereof. The ink is prepared from, by mass, 17-28% of activated dye, 2-10% of a polymeric dispersant, 1-5% of a humectant, 0.5-1% of a pH modifier, 0.1-1% of a sterilizing agent, 2-10% of a cosolvent and the balance deionized water. By adding the polymeric dispersant, a hydrotropy effect is achieved on the dye, the solubility of the dye is further improved, the content of the dye in the ink can be increased, and the prepared dye ink is good in storage stability, good in moistureretention performance, capable of being suitable for ultra-high-speed digital printing (60 meters / minute or above) and especially suitable for cotton and rayon materials.

Description

technical field [0001] The invention belongs to the field of digital inkjet printing, and in particular relates to a reactive dye ink suitable for ultra-high-speed digital printing and a preparation method thereof. Background technique [0002] Digital inkjet printing technology is a product of modern technology applications that integrates computer data processing, precision machinery, and photoelectric information technology, gradually formed with the continuous development of computer technology. Digital inkjet printing technology for textiles began in the 1970s, and completed the transformation from technical models to production applications in the 1990s. As one of the key industries supported by the state, textile digital inkjet printing technology has gradually replaced traditional textile printing technology in the world relying on its obvious green printing technology and unique printing method. [0003] After 2000, textile digital inkjet printing technology has de...
